RIGID ARCHERY BOW HAVING AN ELASTIC STRING 1 Claim. (Cl. 124-22) The present invention relates to improvements u in archery devices and, more specically, to a new and useful improvement in bows, which I call a simplicity modern archery device, for the projection of arrows, and has for its object to provide a device of this description which may be cheaply manufactured and so easily operated as to be readily manipulated by anybody without the application of any considerable amount of skill, and which at the same time will insure considerable accuracy in the directing of an arrow in its flight. A further object of my improvement is to facilitate the packing of the device in a small space when not in use in order that its cost of shipping may be small and that it may be more readily carried by a person using the same.

Another object of the present invention is the provision of a device of the character described which has a new non-resilient bow frame that is to be used in connection with detachable resilient means, and which removes all the shortcomings of the bulgy and expensive hitherto used archery implements and furnishes the means for playing in a new way most fascinating out and indoor games, such as shooting at a mark, target, or balloons high in the air, with a better aim at larger distances than with the old resilient bow hitherto used.

Still another object of the present invention is the provision of a device of the character described which affords the greatest possible accuracy and a perfect balance, which is non-deteriorating and unbreakable, and whose resilient means can be exchanged instantly and without the use of any tools or the application of skill.

Yet a further object of the present invention is the provision of a device of the character described which is light in weight and positively simple in construction, so that it can be manufactured and sold at a very reasonable price, but whichin spite of its comparatively small sizeprovides ample space for ornamentation or for advertising matter to be placed thereon.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be In said drawings:

Figure 1 is a side elevation of a preferred embodiment of my invention;

Figure 2 is a front view of the same;

Figure 3 is a side view of a modication; and

Figure 4 is a diagram showing the device in use. f Similar reference characters refer to similar parts throughout the several views.

Referring first to Figures 1, 2 and 4, the numeral I denotes a non-resilient bow-shaped implement whose end portions are curved at a smaller radius than its main portion 2 and whose outer front periphery is provided with a longitudinal groove 5. Center marks 5 preferably are notched into the center of the main portion 2, and any suitable resilient endless string 1, such as a rubber band or a rubber hose or a coiled spring or the like, is partially embedded in the groove 5. In Figure 1 the resilient string 'I is shown in contracted position in full lines and in expanded position dash-and-dotted. A pin 8 preferably is secured to and laterally extended from the main portion 2 as a rest pin and guide for the arrow I2. The pin B preferably is located above the center of the portion 2. The center and the lower section of the bow-shaped implement I is intended as a handle or gripping section to be held by the left or right hand of a person using the device as shown in Figure 4. I prefer to provide this section, particularly :at its inner side, with notches 9 for assisting the archer in maintaining a grip on the handle. The inner side of the bow-shaped implement I also can be provided with one or more markings or lines indicating the center aim, the upper aim, and the like. I prefer also to reduce the width of the extremity of the portion 3, as may be seen in Figure 1, in order to allow the largest possible vertical movement of the string 'i without friction on the edge of the end portion of the groove 5. The lateral surfaces of the implement I can be provided with ornamentation or with advertising matter or the like.

The string I can be removed from the groove 5, simply by taking it out therefrom, so that strings of different length, or dilerent strength and of different expandibility can be used in connection with one single implement I. The latter is of a comparatively small size, and is primarily flat, so that it can be carried conveniently in a pocket of a garment or in a handbag. It is sturdy and practically unbreakable and can be made of wood, plastic material, aluminum, and the like.

According to the modification of Figure 3 the bow-shaped implement 2| is substantially D- 3 shaped having a main portion 22 which is curved at a larger radius than the end portions i3 and Hi, and being provided with an upright straight handle portion l0. The latter as Well as the inner side of the main portion 22 is provided with notches Il and l@ respectively, and marks IB as Well as a lateral rest and guide pin i8 are provided at the main portion 22 in the same manner as described in connection with the embodiment of Figures 1 and 2. A resilient member li is partially imbedded in the groove l5, which is also arranged in the same manner as the groove of Figures 1 and 2.

In both modifications sharp edges are avoided and the curvature of the groovedv portion of the implement is such that there never will be any damaging friction of the resilient string on sharp edges of the implement.

Since certain changes may be made in thel above article and different embodiments of the invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

An archery device comprising a non-resilient bow-shaped implement whose end portions are curved at a smaller radius than its main portion and which is provided With a longitudinal groove extending entirely over its outwardly curved front side, a pin Which is gradually reduced in diameter toward its longitudinal center being laterally extended from the main portion of said implement above its center, and an endless resilient string being partially embedded and freely slidable in said groove and extended loosely beyond the back of said implement, that main portion section which is beneath said pin being intended as a handle section and provided With notches at its inner side.
